Answer:
50 formula units of NBr3 will yield 75 formula units of NaBr
57 formula units of NaOH will yield 57 formula units of NaBr
Explanation:
The equation of the reaction is ;
2NBr3 + 3NaOH – N2 + 3NaBr + 3HBrO
Number of formula units of NaBr formed when 50NBr3 reacts was obtained from;
2 formula units of NBr3 yields 3 formula units of NaBr
50 formula units of NBr3 will yield 50 ×3/2 = 75 formula units of NaBr
Hence 50 formula units of NBr3 will yield 75 formula units of NaBr
Then;
Since 3 formula units of NaOH yields 3 formula units of NaBr
57 formula units of NaOH will yied 57×3/3 = 57 formula units of NaBr
Hence 57 formula units of NaOH will yield 57 formula units of NaBr
